I have a series 111 XKE and am seriously thinking of putting the
available stainless steel headers on it along with the stainless
free flow exhaust. Has anyone tried this system? Are they difficult
to fit or put on? What was the affect on the performance and sound
of the car? Would you do it again?

I purchased a Series 3 about 1 1/2 years ago here in Atlanta. Dick Maury did the engine work including six Webers, comp cams, hi comp pistons and lightened flywheel. It tested out at over 340hp at the rear wheels and is really quick. Next on my "wish list" is to replace the exhaust system...headers...free flow. I searched the archives and found this thread from several years back. I'm open to and would appreciate any recommendations.

I haven't seen the headers/exhaust only on a Ser. III. Stew Jones recently did a full race modification for Jim Roberge on a '73 Ser. III V-12, which has headers and a whole lot more done to it. I imagine that headers and a freer flowing exhaust would boost the HP, but I'd think you'd need to open up the breathing on the intake side as well to get full benefit from the exhaust side.

You might want to give Stew Jones a call and ask what their experience is. Stew knows more about the V-12 E-types than just about anyone alive.
